11 Claims. ,(cL m-rs) The invention relates generally to casing constructions applicableto various structures. and more particularly to metal window casings designed for use in building constructions.

It is the primary object of the invention to obtain a construction which can be shipped knocked down and in separate sections, butwhich is capable of quick assembly in the field and without the use of special tools or equipment. It is a further object to obtain a construction applicable Figure 91s a front elevation of Figure 8.

Generally described, our improved casing comprises a plurality of sections corresponding respectively to the several sides of the window frame and having the ends of adjacent sections to standard constructions of window frames and forming an interlocking engagement therewith.

Still further, it is an object to avoid the use of screws or other small detachable parts, easily lost,

and to obtain a construction in which the interengaging and locking means are permanently secured to the several elements of the knocked With these objects in view the invention consists in certain general features, and also certain specific features of construction as hereinafter set forth. v 1

While as above stated our improved casing may be used for various purpous, w'e'have specifically described a. construction designed foruse in connection with metal window casings, as shown in the accompanying drawings in which:

Figure 1 is a front elevation showing a window frame and the several elements of our improved casing detached from said frame and from each other;

sides of the web from the flanges B and B. The

of the particular wall to which the casing is ap- 'groove ,E for engaging the bead B and beyond fashioned for interengagement with each other. Also, each section is individually engageable with the corresponding side of the window frame so asto interlock therewith when the sections are 10 As illustrated A is a, metallic window frame of any suitable construction, but as shown formed of comparatively narrow bars of suitable cross section welded or otherwise attached to each other at the corners to form a rigid structure. As

specifically shown, the bars B are of a 2 cross 7 section, including an outwardlyvextending flange B, an inwardly extending flange B, a connecting web B and short flanges or beads B on opposite frame A is only a fraction of the width of the wall in which it is mounted and is therefore supplemented by our improved window casing construction as follows. F

C, C, C and C are the several sections of the casing which correspond respectively to the head, sides and sill of the window frame. Each of these sections is of a width corresponding to the depth from the window frame to the inside plied. Each section is preferably formed of sheet metal and may be provided with an outwardly extending flange D for overlaping the wall and forming a plaster ground and trim. The portion adjacent to the window frame is adapted for interlocking engagement therewith,which may be accomplished by various specific constructions. As shown in Figures 1 to 7 inclusive, the portion adjacent to the window frame'is bent to form a 40 this groove is a portion E lying substantially parallel to the web B Lugs B are struck outward from the web B to overlap and retain the lockwith the bead B.

C, C, etc., forming adjacent sides of 'the casing, are fashioned for interengagement and are also provided with permanently attached locking portion E, the arangement being such that by placing the member C at an oblique. angle the portion E may be inserted beneath the lug or lugs B andby then swinging the member into parallelism with the web the groove E will inter- The ends of the sections means. As shown, the opposite ends of the sections C and C forming respectively the head and sill or jambs, are provided with angle flanges F for overlapping the adjacent side sections 0 and C The latter sections are provided with tongues G which may be either formed integral with the sections or permanently attached thereto as by riveting, weldingor other method. If desired,

the flanges and tongues may be reversed. The

projecting portions of these tongues may then be bent at right angles overlapping the adjacent side and therby locking both sides to each other. Theflanges D on certain of .the sections are extended to complete the rectangle with the corresponding flanges of the adjacent sections. Thus, as shown, the head member C has the extensions D which overlap the ends of the flanges D on the side sections. Also, the sill C is fashioned at its opposite ends to extend beneath the flanges D of the side sections 0' and C", as indicated at D". The sill is also preferably formed with a depressed portion 0* extending longitudinally thereof between the side sections C, C. This forms a groove in which condensation may collect, thereby holding it from draining off the sill and down over the wall beneath the sill.

With the construction as described, the several sections forming the casing being separate from each other and from the window frame, may be compactly arranged. for shipment. Thus where a large number of casings are shipped to a common point for erection, all of the corresponding sections may be nested with each other and will occupy a minimum amount of space during transportation. At the point of erection the sections C, C, C, C may be quickly assembled with the window frames A in the manner previously described. This briefly consists in successively placing the sections at an oblique angle to the frame to engage the portion E beneath the lugs B and then turning the section to extend permndicular to the frame so as to interlock the groove portions E with the beads B The ends of the sections are engaged with each other by inserting the angle flanges F'of one section between the tongues G and end portion of the adjacent section, and in then bending the tongues to overlaparound th corner.

An alternative form of interlock between the casingsctions andwindow frame is illustrated in Figures 8 and 9. In this construction each section has an offset marginal portion E which extendsover the bead B parallel to the web portionB of the window frame, the offset forming a shoulder E bearing against the face of the frame. The portion E has a plurality of depressed portions E with slots E therein. The window frame is also provided with buttons 18 connected to the web portionthereof, the shanks of said buttons being engageable with the slots E. This permits of engagingthe sections with the frame in substantially the same manner as previously described with the construction illustrated in Figures 1 to '7. However, instead of having a continuous groove engaging the bead 3, this bead is only engaged at separated points by the depressed portions E.

In the modified construction shown in Figure 3A the tongue G is formed integral with the member C but is offset from the plane thereof, as indicated at G. The flange F on the member C is cut away at F to receive the offset portion G and after assembly the tongue G is bent around the member C as previously described.
